Arc Haul Ultra 60L Backpack
I’m on the Application Trail right now for the last 30 days and am 100% happy so far. Awesome pack. Probably best on trail.
Long days between resupplies requires a pack designed with ample space and durability. Made from "Ultra 200" material, the ultralight Arc Haul Ultra backpack is innovatively designed to be a true workhorse from the Sierras to the Shenandoah.
Comfortably transfer your pack’s weight to your hips with our custom Curved Carbon Fiber frame system. The frame also creates a gap between your back and the pack allowing for air flow that helps keeps you cool.
Featuring adjustable shoulder straps, an interchangeable belt, and a variety of optional modular add-ons, the Arc Haul Ultra will allow you to tackle those long days on the trail with a durable ultralight backpack designed to fit you.
- Made from Black Ultra 200 fabric with an optional weight-saving accent color in gray Ultra 100 fabric. Ultra fabric features a woven Ultra High Molecular Weight Polyethylene (UHMWPE) face fabric laminated to a waterproof backing. Ultra fabric boasts extremely high abrasion and tear resistance and is the strongest fabric we offer.
- Curved Carbon Fiber Air Stays combined with a Lycra back panel create a gap between your back and the pack. The air gap helps keep your back cool while also preventing items from rubbing against you while hiking.
- Roll-top closure (like our dry bags) keeps water out, and lets you roll down the top as your gear load shrinks. All seams and attachment points are taped, making the pack highly water resistant. We still suggest using dry bags for your important items like your sleeping bag.
- Comfy 3/8" thick by 2.75" wide padded contoured shoulder straps and padded belt. Both the straps and the belt have a daisy chain for clipping on items, and an adjustable position sternum strap is also included. The belt and shoulder straps have 3D mesh on the underside. This gives them a little bit more cushion, and the belt also has more texture for better grip.
- Side pockets are sized to fit 1 or 1.5 liter bottles, or 2L soft bladders. They are positioned low on the pack and slanted forward for easy access without removing the pack. The pockets have drainage holes at the bottom, and elastic that keeps them tight at the top.
- Large stretchy Lycra mesh center pocket is great for quick access items. Mesh also lets you dry wet clothing and gives you a clear view of your gear.
- Side compression straps are made from non-stretchy Dyneema® cord for squishing down the pack volume. They also allow you to stand tall items like trekking poles or an umbrella in the side pockets.
- A top strap, and base straps allow you to lash on extra items to the top or base of the pack. The straps come off if you don't need them.
- The 60L pack size has enough space for 5-6 days of food and ultralight gear. The pack can be compressed down with the roll top and side compression straps for short trips or use the top strap and base straps to lash extra stuff to the outside for long carries.
- All standard Bear Canisters, including the Bearikade Expedition and the BearVault 500 will fit in the upper half of this pack standing on end. There is enough extra girth to either wrap a foam pad around the canister (if you use one) or stand a medium stuff sack vertically beside the bear canister.
- The short and medium size frames will fit into an airplane overhead bin with the top rolled down to the frame. The tall size frame may not fit unless you pop the vertical frame bars out of the pack.
- Our torso height adjustment mechanism is is covered by US Patent No. 9,848,687
- All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
- Made in the USA.
- Our ultralight Curved Carbon Fiber Air Stays keeps the pack stiff so that most weight is carried on the hips instead of the shoulders. The frame pieces and Lycra back panel can be easily removed or replaced.
- The frame is curved to allow air flow and keep your back cushioned from the pack's contents.
- The belt is attached directly to the bottom of the pack frame for the best load transfer.
- The belt is removable and interchangeable. If you lose weight or need to share the pack between people the belt can be swapped out. Watch the belt removal video here.
- The shoulder straps and load lifter straps are attached directly to the frame. Load lifters straps come standard on this pack.
- The shoulder straps can move up or down to adjust the torso height to a perfect fit using our patented torso adjustment mechanism. It works like a conveyor belt. This is great for sharing the pack between people, for growing teenagers, or for resale.
- The belt provides a full wrap around your back. No need for additional lumbar support.
- The belt is done with "V-Style" webbing so that the top and bottom circumference can be adjusted independently. This helps wrap your hips much more securely, and prevents the belt from sliding down.
- Collectively, these features provide the additional load transfer necessary for loads up to around 40 lbs (18 kg).

To measure your torso height, you will need the help of a friend and a string or cloth tape measure.
Most hikers wear their belt near the top of their hips, however, it isn’t uncommon for hikers to position their belt higher or lower.
To ensure you lock in the perfect fit, we suggest putting a belt on over your clothes in the spot where you’d like to belt to ride. Start your measurement at the center of the belt where it meets your spine.
Lower your chin towards your chest. This will cause the C7 vertebrae to protrude at the base of your neck. The C7 vertebrae will mark the top of your torso height measurement.
Using the string or cloth tape measure, follow the curve of your spine up from the center of your belt to your C7 vertebrae. This measurement is your torso height.
The padded portion of the belt is 1" shorter than the listed minimum adjustment. For example a "Medium (30-36 inches)" belt has padding which measures about 29" tip to tip, and has a minimum adjustment circumference of 30". It is the recommended size if your actual measurement is up to 36" however the webbing extends further.
To measure your belt size, pull a string or cloth tape measure tight around the spot you’d like your belt to ride. Choose a belt with a minimum adjustment of a couple inches smaller than your actual waist measurement. This will leave room for you to tighten down the belt if you lose a little weight on trail.
The belts on our Arc Series packs are also removable and interchangeable. This will give you the ability to switch the belt out if your waist size changes or if you order the incorrect size by mistake.

Best so far
The Ultra is better than the arc haul and arc blast. Except for the price. Used about 10 days Hiking so far. The Ultra is made of the new much stronger and tougher Ultra 200 material. 7 times tougher than DCF and 3 times stronger. Its a stiffer, woven material which appears to work well for packpacks. I have an Arc Blast, the Haul and now the Ultra. I found the Blast a little small for longer trips as the Arc takes up space. I never carried much over 15kg max with the arc Haul. That was comfortable. 12 days of food and very cold conditions. If you must, it’s probably good for another couple of kg. And the Ultra will be stronger than the Haul due to the better material. I've always used the lumbar pad with these backpacks. Usually I'm carrying greater than 10kg. I didn’t use the shoulder pads on the haul until recently. I’ve found that the pads are good in hot sweaty weather when i want to un-clip the belt. The ultra is 60 liters and you can get at least as much into it as the haul due to the new style very stretchy Lycra front pocket. The Ultra is about 1cm shorter than the haul. I’d guess that they were chasing a tighter fit with the vertical carbon struts. It has pre-curved carbon vertical struts which make the lycra back trampoline redundant. I think the older style net is is better than the new lycra in that application. Personal preference. Better airflow and less stretchy in the middle. You can also fit the older style bendable struts and net tramp' of the blast and haul to the Ultra if that's your preference. I tried it just to see. Note that the pre-curved carbon struts are very strong but flex only a very little . I have found that if you remove them you need to carefully lever them back into their pockets with a tool like (for example) one of the horizontal struts. Don’t try and bend them. The pack is taped . The tape used could be a little wider I think. I re-taped one short leaking section at the bottom of the front pocket. And broke a carbon strut trying to bend it back into place. Which they most kindly replaced for me. I'm not sure if the pre-curved is better or not. Pros and cons. They're lighter than the older style rods and trampoline combo, stiffer and better airflow (without the redundant new lycra trampoline). But less flexible. It's a choice Happily they have now left out the water bladder port which I’ve always taped up on the other packs. I tried adding an extra horizontal strut at the bottom and found that increased air flow a little. Just playing around. The orange thinner slickline works better on the cinchlines and a longer cord on the pockets make them easier to use. The pockets have metal hooks on them instead of line lock and cord. Pros and cons. The hooks unhook more easily when you want, but sometimes unhook spontaneously or bend/ You can bend them back. The pockets cant fall off due to the middle elastic but it's annoying . I think I prefer the linelocks but that is an easy swap.
Couldn't be happier.
Arc Haul Ultra 60L
Most comfortable pack I’ve worn yet. Carried it about 100 miles so far & am very happy with it. Easy to set up & adjust.
It’s been the only pack I could wear comfortably with over 20lbs due to having back issues from spinal surgery years ago. I have no complaints whatsoever I just wished zpacks would also make this pack in a 24l size for a daypack that would be awesome !
6ft4 This packs is amazing much needed upgrade too the haul the frame is perfect the back mesh is better the shoulder pads are a little wider this material feels super tough i own the original haul this is like its tougher brother im glad i pulled the trigger much superior over big box packs that weigh 6lbs and **** ur hips or shoulders i got about 900 miles n months of everyday use out of my original haul and its still in good shape but the frame of this new pack is far superior just what i was looking for now it is the perfect pack thx zpacks
